How to edit the list of recent categories?

Question

Outlook Categories has 15 recently used lists. Is there any way to edit this?

Older project's categories are included in the list. I want to display new projects.

I would like to do this because it takes less time to select from this list than it does to select "All Categories" and then choose one.

I tried to print the master category list, but the flags in the displayed list don't seem to exist. https://www.slipstick.com/developer/print-list-categories-colors/

There is no information how Outlook maintains the recent categories list. But I think this information could be stored in the same place with categories list. Check out the associated content of your Inbox folder. Read more about that in the Outlook Categories and Color Categories article.

Also I've noticed that categories that were added using Group Policy (by adding corresponding windows registry keys) are displayed first:

HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\nn.0\outlook\preferences
String: newcategories
Value: New Category 1; New Category 2

The same path in the CURRENT_USER hive also works.

HKEY_CURRENT_USER\Software\Microsoft\Office\nn.0\Outlook\Preferences
String: newcategories
Value: New Category 1; New Category 2

Finally, you may consider using shortcuts for categories, so you shouldn't care about the recent categories list.
